Device: Kobo N418 Libra 2
Kobo Libra 2 (N418) stuck in SDP mode - looking for u-boot.imx / eMMC image

Hi everyone,

My Kobo Libra 2 (N418) stopped booting and I've been investigating the issue. When plugged into a Linux machine, dmesg shows the following:

[12535.941539] usb 1-4: New USB device found, idVendor=1fc9, idProduct=0128, bcdDevice= 0.01
[12535.941559] usb 1-4: Product: SE Blank 6SLL
[12535.941565] usb 1-4: Manufacturer: NXP SemiConductor Inc

This confirms the device is stuck in NXP i.MX6 Serial Download Protocol (SDP) mode, meaning the bootloader on the eMMC is corrupted. The hardware itself appears to be working fine.

I've installed mfgtools (uuu) and I'm ready to attempt recovery, but I'm missing the u-boot binary (u-boot.imx) for the Kobo Libra 2 (N418).

I've checked uwuu.ca's unbrick guide and it lists the Libra 2 as "no image available".

Would anyone with a working Kobo Libra 2 be willing to share a dump of their eMMC bootloader, or point me to the correct u-boot binary for the N418?

Any help or pointers to existing threads would be greatly appreciated!

Thanks
